Today, there is a rapid growing demand for graphite electrodes used at steel making factories. Graphite electrodes are expensive materials that are used at steel making factories. Increasing the working longevity of these materials can significantly improve the benefit of steel melting process. Therefore, the increase in the stability of graphite at high elevated temperatures in electric arc furnaces is necessary. The mixture of SiC/TiO2/SiO2 coating can desirably reduce the oxidation of the graphite matrix at high temperatures. Evidently, the SiC/TiO2/SiO2 coating can specially decrease the mass loss rate of the graphite at high elevated temperatures and improve its working longevity in these conditions. Moreover, this coating can effectively improve the stability and thermal shock properties of graphite at the temperatures up to 1000∘C.
